The mines were within an ancient facility owned by warforged of Mechanus. The adventure began in their exodus from these mines, where they fought their way through a few mines protected by Ogres and Moon Giant Lieutenants. They then savagely tried to survive in the cavernous underdark beneath the mines but this led to many encounters with the forgotten dead wandering through these subterranean hollows. As such, the adventurers decided to instead escape into the foothills of Ba’alymm mountains northwards toward the city of Hollow’s Mark. The mercantile capital of the surface of Diomus, it was here that they fought against the dreaded Fenryr giants, a savage bunch of salvagers and tundra hunters.
During their time within the caverns beneath the surface, the adventures meet an Ice Hag and her barbaric kin. The hag folk live closer to the surface but the Ice Hag is a queen in these forgotten caverns. She wants the Eyes of Amalthea and she’ll reward the party if they’re brought back to her. They seek out the Eyes and venture deeper into the caverns, and fight against the spectral ancestors of old. The plague them incessantly but they make their way deeper to the footsteps of an ancient temple carved in the stone face of the glacial caverns.
Here they fight against the undying a spirit of the Uthras, sometimes called a spirit of fire and ice, and steal away from this spirit the Eyes of Amalthea. They trade these eyes to the Ice Hag and are granted aid against the Moon Giant enslavers, locating an entrance to the surface that remains unpatrolled by their former captures.
From this location they march across open tundra, where they meet the hunter Fraek. The adventurers, primary among which were Altair (NM), Briar (TL), Doris (JB) and Fraek (PM), then met some native dwarves that were defeated by Fenryr.
